Srimad-Bhagavatam Lectures

You eat, but you eat kṛṣṇa-prasādam. Don't eat anything else. Then gradually your senses will be conquered. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234). If you want to realize God, first of all you should engage your tongue in the service of the Lord. It is very astonishing that "Engaging the tongue I become perfect?" Yes. The beginning is the tongue because tongue is the greatest enemy. People are going to hell on account of being unable to control the tongue. Therefore one has to control the tongue.

Lecture on SB 6.2.5-6 -- Vrndavana, September 9, 1975:

Kṛṣṇa consciousness movement is therefore giving them knowledge. The first knowledge is that we are trying to convince everyone, following the footprints of Lord Kṛṣṇa, as He wanted to convince in the very beginning, that dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā (BG 2.13). This is the first knowledge. One should know that he is not this body. He is spirit soul, different from this body. He is living within this body. This is called knowledge. And at the same time, he should be supplied the necessities of the body. Yāvād artha-prayojanaṁ. Nirbandhe kṛṣṇa-sambandhe yukta-vairāgyam ucyate. Anāsaktasya viṣayān yathārham upayuñjataḥ Viṣayā. Viṣayā means we need something for our sense gratification. That is allowed. We don't say that "You don't eat." No, you eat, but you eat kṛṣṇa-prasādam. Don't eat anything else. Then gradually your senses will be conquered. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234). If you want to realize God, first of all you should engage your tongue in the service of the Lord. It is very astonishing that "Engaging the tongue I become perfect?" Yes. The beginning is the tongue because tongue is the greatest enemy. People are going to hell on account of being unable to control the tongue. Therefore one has to control the tongue. And controlling tongue means you engage the tongue in the service of the Lord. How? Tongue means you can speak with your tongue and you can eat with your tongue. So engage the tongue chanting Hare Kṛṣṇa and preaching Kṛṣṇa consciousness. This is service. And tongue wants to taste. Give him kṛṣṇa-prasādam, very nice. So as soon as you engage your tongue in these two business, then naturally you become purified and your senses become also purified. Then you come to the real platform.
